Publisher's Synopsis
Excerpt from Statistics of Mines and Mining in the States and Territories West of the Rocky Mountains: Being the Seventh Annual Report
Of equal economical importance with new discoveries of valuable ores, though of a less sensational character, are the steady improvements in the art Of metallurgy, by which it is becoming possible every year to treat with profit a larger proportion of ores extracted from our mines. I have continued to give much attention to this subject, being ably sup ported by my assistant, Mr Eilers, with whom it is a. Specialty; and the efforts which I have put forth, through a series of years, to furnish use ful records and suggestions to American metallurgists are, I am glad to know, not unfruitful. A class of men has gradually, but surely, come into the management of important works in this country to whom such information is welcome, because they know how to make use of it; and in return for such a service they freely put at the disposal of him who renders it the results Of their own experience, as the means of still greater usefulness. The pages of my reports bear very gratifying evidence Of this reciprocity Of feeling - a condition indispensable to rapid and thorough advances in any art involving the application Of science.
Very respectfully, your obedient servant, R. W. Raymond, United States Commissioner of Mining Statistics. Hon. B. H. Bristow, Secretary of the Treasury.
